-

A) Logarithmic, $f ( x ) = a + b \ln x$
B) Polynomial, not quadratic
C) Exponential, $\mathrm { f } ( \mathrm { x } ) = \mathrm { ab } { } ^ { - \mathrm { x } }$ or $\mathrm { f } ( \mathrm { x } ) = \mathrm { P } _ { 0 } \mathrm { e } ^ { - \mathrm { kx } } , \mathrm { k } > 0$
D) Exponential, $\mathrm { f } ( \mathrm { x } ) = \mathrm { ab } ^ { \mathrm { x } }$ or $\mathrm { f } ( \mathrm { x } ) = \mathrm { P } _ { 0 } \mathrm { e } ^ { \mathrm { kx } } , \mathrm { k } > 0$
